SPINDLE FOR SPlNNlNG-FRAMES.

SPECIFICATION forming part of Letters Patent No. 253,025, dated January 31, 1882.

Application filed July 29, 1881.

T all whom it may concern:

Be it known that 1, RIMMON C. FAY, of Mil ford, Worcester county, State ot Massachusctts, have invented an Improvementiu Spindles for Spinning-Frames, of which the following description, in connection with the accompanying drawings, is a specification.

This invention in spindles is an improvement on the class of sleeve-whirl spindles such as represented in United States Patent No. 227,129, granted to Rabbeth, dated May 4,1880, to which reference may be had.

My inve'ntion has for its object to provide the supporting-tube with a catch so located thereon as to eng-age a shoulder within the -whirl-sleeve and prevent the spindle being lil'ted during the usual straiu of doffing, yet permitting the spindle and sleeve-whirl to be removed from the supporting-tube, when it is desred to do so for any purpose, by deflecting or draw1ng the spindle and sleeve whirlin the proper direction. The pintle of the spindle is inserted in a bolster-bearing surrounded by an elastic or yielding packing, so that the spindle and bearing may be tipped or turned backward in the supporting-tube far enough in an opposite direction from which it is tipped when the bobbns are being doffed to cause the edge: of the shoulder of the sleeve-whirl 0 to fall in a line outside ot'-the end of the catch extended from the supporting-tube, when the shoulder of the sleeve-whirl may be 1itted above the end of the catch. The diameter of the circular space between the shoulder of the 5 whirl-sleeve and the external diameter of the supporting-tube and the length of .the catch rdially from the said tube are such that the shoulder strikes the support just after the sleeve-whirl is moved farenough for the shoul- 0 der thereon (the sleevewhirl being lifted) to pass the said catch, thus avoiding such accidental strain on the spindle as would detlect it or put a permanent bend in the same.

Figure 1 represents in elevation and verti- 5 cal section a sufficient portion of a sleevewhirl spindle, its supporting-tube, and parts located thereon to illustrate my invention; and Fig. 2 is across-sectionthereof on the dotted line 00 90 of Fig. 1.

The spindle a, its attached sleeve-whirl b,

supporting-tube a, bolster d, and elastic pack- (No model.)

ing e, and foot-stepf are all as usual in spinning-frames.

l have provided the lower end ot the sleevewhirl with an inwar lly-extended shoulder, 2, and the support c with a catch, 3, which, when the spindle a stands in vertical position, extends over the verticalinner edge ot theshoulder 2, as shown in Fig. 1. This catch 3 will be located at the front side ot the tube c, so that 6o as the spindle is moved or tipped a little in the direction of the arrow 6 in dotfing (see Fig. l) the shoulder 2 will not be moved away from the catch, but, on the contrary, toward it, thus effectually preventing the spindle from being lifted from the holster or tube c.

When it is desired to remove the spindle and sleeve-whirl from the bolster and tube c the spindle will be tipped in the direction of the arrow 5, which will move the lower end of the sleeve-whirl sufficiently far in the direction of the arrow 6, Fig. 1, to bring the edge of the shoulder 2 against the tube c, or 1'ar enough to aftbrdasutficieut space between the edge of the said shoulder and the catch 3 to permit the shoulder of the sleeve-whirl to rise past the said catch, as will be understood. The yielding packing aids materially in insuring efficiency ot operation of the catch and shoulder of the slceve-whirl. The catch will preferahly be undercut to iusure its better engagement with the shoulder 2 of the sleevewhirl, it being suitably shaped to correspond with the under side ot the catch.

The bolster herein shown is represented as seotional; but such a bolster is not of my invention.

I claim- The spindle and its attached sleeve-whirl, provided with the shoulder 2, combined with 0 the bolster, the elastic packing external to the said bolster, and the bolster-supporting tube c, provided with the catch 3, to co-operate with the shoulder 2of the sleevewhirl, asdcscribed, and for the purposes set forth.

In testimonywhereofIhavesigned my name to this specification in thepresence of two subscribingwitnesses.
